EXP(x)
- where x is the number .
Description
- This function gives the e raised to the power of number.
- In EXP(x), where x represents the exponent of e, or e^x.
- The approximate value of the constant e=2.718281828459045 and it is equal to e^1 or EXP(1).
- It is called the mathematical constant or Euler's number or Napier's constant.
- Also it is the base of natural logarithm.It can be calculate in the sum of infinite series:
- e=1+(1/1)+(1/1.2)+(1/1.2.3)+(1/1.2.3.4) +...
- And the inverse function of the natural logarithm function is the exponential function:
- f -1(x) = e^x.
Examples
- EXP(1)=2.718281828459045
- EXP(0)=1
- EXP(-5)=0.0067379469990
- EXP(6.3)=544.5719101259
